EDWARD GURNEY, OF TORONTO, ONTARIO, CANADA.

HEATER.

SPECIFICATION forming part of Letters Patent No. 389,459, datedSeptember 11, 1888.

Application filed March 17, 1888. Serial No. 267.501.

To all whom it may concern.-

Be itknown that I, EDWARD GURNEY,Of the city of Toronto, in the countyof York, in the Province of Ontario, Canada, manufacturer, have inventeda certain new and useful Improvement in Heaters, of which the followingis aspecification.

The object of the invention is to produce a hot-water heater in whichthe water may be heated either by heat produced by fire in its fire-potor by steam-heated pipes introduced into the water-spaces of the heater;and it consists of a hot-water heater in which a coil or coils of pipingis introduced into the water space or spaces of the heater, lhe wholebeing arranged substantially as and for the purpose hereinafterspecified.

The figure is a sectional elevation of a hotwater heater constructed inaccordance with my invention.

The original object of my invention was to produce a hot-water heaterfor railroad-cars which would utilize the exhaust-steam from thelocomotive for the purpose of heating the water in the heater without inany way interfering with the firepot or effectiveness of the heater asan ordinary hot-water heater, so that should the supply of steam beaccidentally cut off the fire might be immediately started in thefire-pot and the furnace used in the ordinary way.

On examination of my invention it will be understood that a heaterprovided with my improvements may be used' in any place whereexhaust-steam can be secured.

In the drawing, A represents a steam-pipe, and B coils of pipe insertedin each water-compartment O, and all connected with the verticalsteam-pipe A, which extends to a point below the fire-pot grate, whereit enters the water-space formed around the ash-pit, and is coiledtherein, as shown, the steam in the pipe passing out through the cock D.The upper (No model.)

portion of the steam-pipe A will of course be also provided with asuitable cock, so that the supply of steam may be cut off when desired,or the pipe closed should the steam be cut off. Each water-compartment Ois connected to the one above it by openings 0.

It will be noticed that the ordinary fire pot, h

E, remains in position and is always ready for use, and in applying mydevice I prefer to have all the water-spaces connected together, so asto insure perfect circulation.

From this description it will be seen that the introduction of the pipesB will have no efl'ect upon the satisfactory working of the furnaceshould it be necessary or desirable to utilize its ordinary fire-pot.Consequently by the introduction of myinvention the exhauststeam of thelocomotive may be used for warming the cars of a train, and should thesupply of steam he accidentally or intentionally cut off the heater maybe used in the ordinary way.

I do not herein claim a heater, acirculating system in operative contacttherewith, and a steam or other heater also in operative contact withthe circulating system, as that is not my invention.

What I claim as my invention is- A hot-water heater provided with anordinary fire-pot and consisting of a series of water-compartmentshaving their water-spaces all connected together, in combination withpipes arranged within the water-spaces, substantially as described,whereby the steam may be introduced into the pipes and pass through thewater while in said pipes for the purpose ofheating the water by contactwith said pipes, as set forth.

Toronto, March 10, 1888.

EDWARD GURNEY.
